Description
- 1. Field of the Invention
- The present invention relates to a temperature-measuring manometer, and more specifically relates to a manometer capable of measuring blood pressure and the temperature of an environment.
- 2. Description of the Related Art
- Blood pressure is measure of the pressure of blood flowing through a blood vessel wall. Moreover blood pressure comprises a systolic pressure and a diastolic pressure. An unusual blood pressure is usually a warning of a serious illness such as apoplexy, heart disease or uremia. Therefore measuring blood pressure assists medical professionals in determining if a patient is suffering from an illness.
- A major part of measuring blood pressure is inflating the arteries bag so that it compresses the patient's blood vessels. Using a stethoscope or other inductors also measures blood pressure, may be either a mercury sphygmomanometer (Sphygmomanometer) or an electronic automatic sphygmomanometer (Auscultation Sphygmomanometer). All these devices have in common the need to inflate the arteries bag so as to prevent blood flow. By increasing the pressure against the arteries, blood ceases to flow through the blood vessels so that the patient's blood pressure can then be measured. By decreasing the barometric pressure, the blood may then resume its ordinary pulse and flow. When the first sound of the N.S. Korotkoff sound effect is detected, the device reads the pressure gauge as the Systolic Pressure, then gradually reduces the pressure of the arteries bag, the vascularization channel widens, and the blood resumes its normal smooth flow through the blood vessels, as the arteries bag pressure decreases, the channel gradually opens. When the N.S. Korotkoff sound effect begins to weaken, the last sound is recorded as the Diastolic Pressure.
- A Sphygmomanometer user needs to have their blood pressure regularly measured. However, temperature changes in the environment affect blood pressure, thus creating abnormalities. As such, it will be difficult for a doctor to judge whether an abnormality is due to a change in the patient's condition or due to environmental changes. To compensate for this, a sphygmomanometer simultaneously takes an environmental temperature measurement as it measures a patient's blood pressure.
- Accordingly, the objective of the present invention is to provide a temperature module that measures the temperature of the environment, and, after the user has measured the patient's blood pressure, records and displays the environmental temperature and the patient's blood pressure.
- The temperature-measuring manometer of the present invention obtains a patient's blood pressure through a pressured sensor and obtains the temperature of the air through the temperature module. The information is then transmitted to an A/D converter coupled to the pressured sensor and the temperature module. The A/D converter receives the blood pressure signal and the temperature signal and transforms the analogue signal to a digital signal. A microprocessor coupled to the A/D converter for processing the digital signal of the blood pressure signal and the temperature signal outputs the blood pressure data and the temperature data. This data is then transmitted to a memory unit coupled to a microprocessor for storage and transmission to a display unit.
